paste this in user CSS:

@media (min-width: 50rem) {
body[data-st-fullscreen="true"] .post-index .sidebar { display: flex; grid-area: unset; }
}

it'll make the stuff appear at the bottom of the page when in full-screen mode, like how it looks on mobile. maybe not an entirely perfect solution, but better than it being entirely gone.

Switching to mobile mode basically brings it back. So until then, I’ll have to stick with mobile…
